n 'Ihis inventionrelates to a wrapping machine. *l

The chief object of the invention is to wrap rolls, bricks or blocks of material such as butter or the like mechanically and automatically without manual engagement.

The chief featurek of the invention consists in the progressive'feeding of butter blocks or the like to the wrapping machine in predetermined position and in timed relation with the supplying of the wrapping material and thereafter automatically wrap the article with the wrapping material upon continued movement of the several'parts of the machine in cyclic'operation and following ywhich the wrapped'article is automatically ejected.

The full nature of the invention will be understood from the accompanying drawings and theV following description and claims:

In the drawings Fig. 1 is a side elevation of the machine with parts broken away and shown in transverse section. Fig. 2 is a top plan view of the machine with the final folding guide and wrapped carton retainer removed. Fig. 3 is a transverse sectional view taken on line 3-3 of Fig. 1 and in the direction of the arrows and is of the block advanc- 30 ing mechanism.

Fig. 9 is a similar view of the same parts in the third and fourth wrappingpositions. Fig. 10 is a similar view of the same parts in the final wrapping position. Fig. y11 is a view of the same parts showingthe block completely wrapped and ready for discharge. Fig. 12 is a side elevation of a wrapping Wheel adapted for roll vtrapping. Fig. 13 is a top plan view thereo In the drawings 10 indicates a platform upon which is detachably and preferably adjustably mounted a supply framework 11. A pair of said frames is positioned side by side and each terminates in an oppositely positioned slide in the form of an angle iron 12, the same forming an open channel between which is mounted an actuating plate 13 carried by a framework 14 which is mounted on the bearings 15 eccentric to the shafts 16. Each shaft 16 carries a disc 17 upon which is mounted the eccentric crank pin 18. Crank pin 18 and both discs are connected together by the tie-rod 19. One of the shafts 16 mounts a pulley 20 driven by link belt 21 or equivalent means driven by pulley 22 carried by shaft 23, which shaft is mounted in the bearing 211 and is driven through the belt 25 by motor 26 to an ad jacent pulley 27 also on shaft 23. The channel supports blocks of butter or the like 30 at the ends. Since butter is cut to the same predetermined length for quarter, half and pound packages or cartons, a fixed width of channel is utilized. Each rotation of shafts 16 cause the butter blocks to be elevated from the channels 12 by the plate 13, carried upwardly and forwardly and thence deposited upon said channels 12 and retained thereby during the remainder of the return and lowering movement of the median member 13. In this manner the blocks of butter are advanced along the table or feeding mechanism.

Adjacent the end of the table there is mounted a movable guide 31 which is retractable with a support or platform 32 carried by stem 33 mounted in the guide 34.

Said stem 33 terminates in a roller 35 enf'l gaging cam 36 carried by and rotatable with shaft 23 and in predetermined relation. Thus, the block of butter at the predetermined time is permitted to advance along the channel and be positioned upon the elevator 32, the block being aligned in proper position by the back plate 37. After the block has been positioned on the platform 32 by the advancing means previously described and the roller has been elevated by means opening or socket'45 of the wheel 5(),the'spefV ciiic description of which will be given later.

The shaft 23 includes a crank 46 and the combination link construction 47 through` pin V148 is adapted tov reciprocate the lever 44 towards and away from the wrapping drum 50. Mounted in the machine frame work 49 is a pair of plates 50 which form drums and are carried by the shaft 48. Said plates are apertured as at and are joined together by a pair of parallel socket forming members 47. In the 180 degrees of Arevolution of the wheel from the loading to the discharge position diametrically opposite therefrom, the Wrapped carton successively is supported by the lower face 47, the rear edge 45 of the notch in each of the wheels 50 and the'upper face 47, reference being had to Fig. 6. l

Theopenworkwheelconstructionemployed is utilized since a pusher plate or ejector 51 is lmovable from the dotted line shown in Fig. l to the full line thereof, said pusher bar being carried by the rod 52 'slidably supported in guide 53, and said rod 52 is connected to the bracket 43 and thus simultaneously reciprocable with and to the same degree as the feeding plate 40. Thus plate 51 constitutes an ejector for the wrapped blocks of butter. Positioned adjacent the discharge position is a supporting block 54 and as the blocks are successively discharged they pass on to a belt 55 or other suitable conveying` means from which they may be removed and assembled into larger packages.

Y Between the plate 37 and the wrapping Wheel there is provide-d a trough 56 and as shown clearly in Fig. 6, a sheet of wrapping material such as paper 57, is receivable. by said trough and engaged by the block of butter 30 when the block of butter 30 is projected into the block compartment or socket formed bythe recesses 45 and plates 47. Thus three sides of the block are simultaneously covered. This is shown in Fig. 7. Thereafter the wrapping wheel is rotated a slight arcuate distance clockwise and as a result thereof the lower projecting edge 58 of the paper 57 is caused to lie against the unwrapped face of the butter carton. Simultaneously therewith the paper adjacent the opposite and lower ends of the butter block is engaged by the tongues 59 and a part of the end wrap isobtained. Thereafter, see Fig. 9, the rotation of the Wheel is reversed and in the reversal the upper free end 60 engages the cam or tongue 61 and is caused to lie adjacent the other folded end and complete the wrapping along the sides. Simultaneously with this movement the tongue 62 engages the oppositeV portion of the wrapping from that engage-d by the tongue 59 and forms the opposite fold which lies adjacent that formed by said tongue 59. Continued rotational movement in a counter'clockwise position of said wheel ythereupon causes the Vback portion of the end of the wrapper indicated'at 63 in Fig. 9, to follow in the-slot 64 which is suitably formed so that it will not sever the same from the re-y rotation of the wheelfwill position the car- Y ton fully Wrapped and ready forjejectment by the ejector 51.V y

lThe mechanism for securing the aforesaid step by step rotation and reversal ofthe wrapping wheel is shown in'Figs. land 5. Rigid with the shaft 48 are a pair of oppositely directed ratchet wheels 70 and 71. Oscillatably mounted on Vsaid shaft is a bracket l7 2 which in one arm yieldingly supports a dog 73 and in another arm yieldingly supports another dog 74, said dogs being oppositely arranged and being associated with the oppositely positioned ratchets, dog 7.3 cooperating with the ratchet 71 and dog 74 cooperating with ratchet 70. The oscillating bracket 72 is'connected by link75 tok a lever 76, the p same having an adj ust-able connection, see Fig. 1 and being fulcrumed at 77. Said lever terminatesrin a follower 78 positionable in an interior cam 79 having the reversing portion 8K0, the dwell portion 81, the elevational portion 82 and the lowering or returning-portion 83. The 'dwell portion 80 through -th'e inaio strumentality of the -aforesaidconnection, y

causes the reverse rotation of the wheel from the position shown in Fig. 7 to the position shown in Fig. 8 and the portion 82causes rotation of the wheel in the counterclockwise direction for the final wrapping of the block.

The dwell portion 81 of the cam secures a .ce the carton in Fig. 11. Thereafter continued Y rejector passage. `Adjacent each end of the trough and.` extending inwardly is a pair of spring retainers 148 permitting of roll recep- CTI tion but preventin roll rotation thereby insuring Wrapping o the roll in theoscillatory movement of the Wheel. Said springs are also spaced apart to clear the ejector mechanism and may be formed integral With the U- shaped roll adapter insert, the free ends of the latter having sufficient resiliency to maintain the adapter in pocket 45 by engaging the blades 47 thereof.

The invention claimed is:

l. In a Wrappino'f machine, the combination of a Wheel including an article r-eceiving pocket, meansk positioned adjacent the peripheral path of said Wheel, additional means positioned adjacent the sides of vsaid Wheel for simultaneously engaging an article Wrapping for folding the same, means for rotating said Wheel for securing said Wrapping, and means for rotating said Wheel in opposite directions for Wrapping.

2.
